further high grades additional fourteen target, page-27

Is UMC still targeting 100Mt DSO Marra Mamba?

You bet they are and I will give you my reasons!

This is not back of the envelope stuff but calculations based on RockWorks, one of the best geo programs available.

As you have seen from today's announcement, Barry has more accurately defined the Railway target area, which is now 1,882,000 sq mtrs.

Based on the results to-date, I have prepared the following two resource calculations:

(A) 143.6Mt at 58.92% Fe (sg 3.064) for an avg intersection of 24.9 mtrs.
1,882,000 x 3.064 x 24.9 = 143.6Mt at 58.92% Fe

(B) 112.5Mt at 60.98% Fe (sg 3.17) for an avg intersection of 18.85 mtrs.
1,882,000 x 3.17 x 18.85 = 112.5Mt at 60.98% Fe
